IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent N0. 186.213, dated January16, 1877 application filed November 20, 1876.

To all lwhom it may concern:

Be it known that I, WILLIAM O. NORTH, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Vapor-Burner; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in vapor-burners.

In the drawing, Figure 1 shows a view, in longitudinal section, of `aburner according to my invention; Fig. 2, a bottom view of the burnerproper.

My invention consists in the following parts and combinations, ashereinafter specified and claimed, wherein- A is the crown-piece orburner proper, constructed, as shown in thev drawing, of a series ofsteps, c, provided with lateral perforations for the exit of the vaporto be consumed, and from which the flames are emitted. Y

It will be observed' that the inner contour ofthe burner A is alsoformed in steps corresponding to those upon the outside; and hereinconsists an important feature of this invention. for, by this provision,the current of vapor is distributed and broken up in such a mannerasthat a uniform and equal exit force is given to the escaping vapor. Bythis means not only a steady and uniform dame is attained, but one whichburns silently and without the blow 7 common in a large class ofvapor-burners.

The thimble Bl of the stem Bis made to project a short' distance abovethe base-plate of the burner A. This construction also assists inaccomplishing a uniform and quiet combustion.

In the base-plate a of the burner A is provided a circle of perforationssurrounding the thimble B1. These I term-superheaters, their ofce beingto heat the parts adjacent beneath, and thus accomplish the vaporizationof the liquid to be consumed.

The thimble Bl, the primary heating-cup B, the stem B, with itspin-valve C and its attachments, are not materially dierent in my devicefrom those parts as heretofore ordinarily constructed.

Heret-ofore trouble has been experienced in the escape of theburning-fluid at the bottom of the rod of the pin-valve C, and one ofthe principal features of my invention resides in my method of obviatingthis difficulty, which consists in the packing-cup D, preferably placedat the base of the stem B. This packing-cup I fill with soap, glue, orsome equivaient plastic material which will not be acted upon by theburning-duid. This packing affords a complete stop to the escape of theburning-Huid.

I do not conne myself to any particular construction of the packing-cupD, nor do I confine myself to the employment of soap or glue, as anyequivalent of those substances may be employed.

What I claim isl. The combination with the T- coupling, having ascrew-threaded valve-stem guide attached thereto, of the screw-threadedvalvestem, and packing-cup or gland D, the latter filled with soap orglue, substantially as and for the purpose set forth.

2. The combination, with the burner A constructed with a dependingcollar, of the thimble B1, formed with an annular flange, Whereby it. isadapted to be supported and firmly secured beneath the burner,substantially as and for the purpose specified.

3. In a vapor-burner, provided with means for injecting' a current ofgas into a receptacle wherein the gas is commingled with oxygen, theburner A, formed of two or more perforated cylinders, decreasing in sizetoward the end ofthe burner, the lower cylinder provided wit-hperforations in its base portion, to allow air to be drawn in and mixedwith the gas as it is broken up by the angular ledges formed by theinner surface of the burner, substantially as and for the purposespecied'.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM C. NORTH.
